Liveblogging: Tech Women Rule!

I am moderating and liveblogging the Professional IT Community Conference panel called Tech Women Rule! Creative Solutions for being a (or working with a female technologist. One point to keep in mind: The goal is not equality for equality’s sake. The goal is to have a diverse range of experience to make your company/project/whatever the best it could be. That being said, these issues are not just around women; they are about anyone who is “different”, whether it’s race, ethnicity, gender, sexual orientation, cultural. So what are some of the solutions?

Liveblogging: Seeking Senior and Beyond

I am attending the Professional IT Community Conference – it is put on by the League of Professional System Administrators (LOPSA), and is a 2-day community conference. There are technical and “soft” topics — the audience is system administrators. While technical topics such as Essential IPv6 for Linux Administrators are not essential for my job, many of the “soft” topics are directly applicable and relevant to DBAs too. (I am speaking on How to Stop Hating MySQL tomorrow.)

On the Difficulty of Data Migrations (Especially to NoSQL Databases)

I’ve been reading a lot of NoSQL blogs recently, and one thing that bothers me is that many of the leading NoSQL bloggers seem to have very different experience in operations that I’ve had. Here’s an example:

“Oracle RMAN 11g Backup and Recovery” book

One of the most critical skills of any Oracle DBA is the ability to prevent a system crash and to restore and recover the system in case of a disaster. The “Oracle RMAN 11g Backup and Recovery” book by Robert G. Freeman and Matthew Hart is a resource that can definitely help to acquire the skill. I recently received my early copy of it, and am honored to have contributed to Chapter 5 “Oracle Secure Backup” for it.

Stats Overflow

Recently I’ve been puzzled with the performance difference observed between 11GR1 and 11GR2. As part of the investigation I’ve decided to compare session stats from both 11GR1 and 11GR2 and found that there is a big difference for session cursor cache hits. But the number of session cursor cache hits I’ve been observing in 11GR2 just didn’t made any sense while being absolutely fine in 11GR1. An overflow was certainly a possibility, though in 2010, it’s not like someone should be counting every bit especially if they didn’t in 11GR1! Anyway it was worth a shot so I’ve decided to check it out…

Installing TOra with Oracle Support on Ubuntu 10.04 (Lucid Lynx)

Once again into the breach. The release of Ubuntu 10.04 is at hand. I’ve been playing with “Lucid” for a couple of months now but since we’re in beta2 with the release candidate soon to follow, I thought I would really sit down and get my normal app stack working including TOra. All in all the instructions are mostly the same as last time around, with a couple of new improvements, caveats and quid pro quo.
